shed: this isn't a minus, for me, as long as it's MPP. allows for multiple stages, something you can't get in a club where if you don't like the band on stage you're pretty low on options. you can get some sun and fresh air. lots of food and drink options. sometimes there a market.
same day: i don't think this is a bad thing. it's a long day and you need to pace yourself (well, some of us do), but it makes for a one-day musical vacation.
shorter sets: this is a definite and big negative, can't argue there. FM should hopefully get an hour, maybe even an hour and a half if they headline the second stage. getting only 40 minutes of clutch would/will suck. hey seth...
